Cashless 2 (with cashless licence 2)
With the cahsless licence 2 activated, the W25T can manage two cashless systems
on the MDB port. To do so, one system is on address 1 (standard on any cashless
system) and the other on address 2. You must also set the type of your cashless 2
to either
Prepaid or Credit . The card reader itself must be able to work on either
on cashless address #1 or #2 and that it allows you to change that address into the
internal settings of the reader.
Card Revalue Limit
If you have a prepaid cashless system, it is possible to revalue the user card with
the help of the other payment peripherals connected to the MDB port. Those
other peripherals are the coin acceptor, the bill acceptor and the credit/debit card
system. The limit must always be inferior by $20 of the same set-up in the prepaid
cashless system. If the maximum card value in the prepaid system is set to $50, the
card revalue limit must not be higher than $30 so that it does not go over the $50
limit in the case someone inserts a $20-bill.
To revalue a prepaid card, the customer simply inserts his prepaid card into the
reader and then adds money. Once done, simply eject the prepaid card. All money
inserted is now encoded on the card.
Card to card
If you have both a credit card and a prepaid card readers on the machine, it is pos-
sible to add money to the prepaid card using the credit card.
To revalue a prepaid card, the customer simply inserts his prepaid card into the
reader and then swipe or present his credit card to the other reader. Once done,
simply eject the prepaid card. The preauthorized credit card amount is now en-
coded on the prepaid card.
